python - Check if widget exist(Tkinter) -


I want to check that before I delete it, any widgets (such as a rectangle drawn on the canvas) exist is.

Here's my problem: I have two ways, which remove the rectangular I using a bind is connected to the button -1 (when it is clicked it rectangles ) And the second method removes a rectangle, if it is not clicked on a specific time ( Widget.after ). I would like to check whether the rectangle exists in the second method because I want to count the rectangle which was not clicked and the way I can think it has already been removed or not. Is there any way of doing it? Of course, I can set a variable inside the button-1 event handler and see it in another way. But just wanted to know that if tunicator provides a method like "item existence"

Edit: OK, I just got a move if I got itemconfig on deleted widget , I get empty set. I use that value to see if any widget has already been removed or not. I'm not sure that this is a great way to do it though.

I think that you can use all items on your canvas to obtain a tuple You can then see if your particular item is in that Tupl example: 

  item in my_canvas.find_all (): my_canvas.delete (item) Other: Print ("No Item on Canvas")

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
